Allow empty values in InspIRCd 2.0 mode strings within CAPABILITIES

Browse Source 
Skipping over empty values in the commasepstream can put the mode adding
logic out of order (eg. ignoring the first two tokens when they are the
needed tokens). Most modes are already added by being explicitly checked
for, but the "unknown" or "extra" modes are added here.
